Programs built on Claude Code through its SDK (the toolkit developers use to run Claude Code from their own code) can listen for these events. A further group of tasks now sends no `task_started` event, and those tasks are also left out of the list of active tasks.\n\n**Why**\n\nIf you build on the SDK and count or display tasks from these events, you may see fewer of them than before.\n\n- Area: SDK\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: yes"}
